Hi!

I'm capturing data with ethereal for an operator and the problem I came across is that all the captured packets appear twice. The reason I believe is simply that there is another port in monitoring mode on the same vlan. Now the operator do not want to switch the second port off for I don't know what reason, so I wonder if anyone knows a way to set up a capture filter to get rid of these hardware duplicates and have a clean trace file.

Thanks,
Gianluca
